Xiang Kun sensed Mr. Liang's emotions of terror, sorrow, and then anger, even madness in his dream. He then witnessed a brief battle.
Clearly, Mr. Liang wanted to seize the body of Academician Shen and subdue the beautiful woman, but he failed and was beaten brutally, until he was on the brink of death.
According to ordinary human judgment, Mr. Liang should be undeniably dead—he had his heart gouged out and tossed before his face.
However, seeing as Mr. Liang was still alive, he obviously had not been killed or devoured at the time.
From Xiang Kun's perception of the dream, the moment Mr. Liang opened the lab door, the beautiful woman must have already been drinking blood.
That might explain why she did not completely kill Mr. Liang or drink his blood—she had almost finished consuming Academician Shen and needed to leave as soon as possible to find a safe place to sleep and complete her transformation.
